Description

[Detailed description of the invention] The present invention relates to a separator guide used to separate the metal strip when winding the metal strip after slitting (cutting the metal strip into multiple thin strips). .

To manufacture a narrow metal strip, first make a wide metal strip, slit it to the desired width using a slitter, and wind it using a tension reel to create the final product. is a common method. Now, this winding process will be explained using the schematic diagram shown in FIG. 1 of the attached drawings.
is separated by a separator guide 5 supported by a separator guide lifting device 4 disposed between guide rolls 2 and 3, and taken up by a metal band take-up reel 8 via deflector rolls 6 and 7. It will be done. In this case, separator guide 5
is provided for the purpose of maintaining a constant interval between each slit metal strip 1 so that the slit metal strips 1 do not interfere with each other and cause scratches or winding defects. It is something. Conventionally, as this separator guide 5, a device as shown in FIG. 2 has been used. That is, the separator shaft 1 is rotatably supported by a bearing 9.
Spacer 1 of desired width engaged with outer diameter of 0
1a, 11b, 11c, 11d, 11e, 11f
Disk guides 12a, 12b, 12 respectively between
c, 12d, and 12e are arranged and fixed to the separator shaft 10 by tightening them from both sides with tightening nuts 13. These disc guides 12a, 12b, 12c, 12d, 1
2e, the metal bands 14a, 14b after slitting,
14c and 14d to provide a constant spacing between each metal band.

However, such conventional separator guides have the following drawbacks. That is,
When changing the value of the metal strip 14 to be manufactured, it is necessary to rearrange the spacers 11 in order to change the width between the disc guides 12 accordingly, but this rearranging work requires a lot of man-hours and time ( for example,
(about 0.5 to 1 hour), which caused a decrease in the operating rate of the slitter. In particular, when the product lot is small, the number of recombinations increases, resulting in a significant decrease in the operating rate. Further, this reassembly work requires removing and replacing each heavy spacer 11, so the conventional method is not preferable from the viewpoint of safety.

An object of the present invention is to obtain a separator guide that eliminates the above-mentioned drawbacks of conventional separator guides.

Hereinafter, the present invention will be explained based on FIGS. 3 to 5 of the accompanying drawings showing one embodiment thereof.

A hollow separator shaft 20 is rotatably supported by bearings 22 at small diameter shaft portions 21 at both ends. In the outer wall of the hollow part of the separator shaft 20, vertically elongated holes 23 are provided at positions that divide the circumference into four equal parts at regular intervals in the axial direction. The positions of the holes 23 in the circumferential direction are 45
It is placed at a shifted position. Further, a substantially convex-shaped lug 24 having a protrusion corresponding to the hole 23 is inserted into all the holes 23 from the inside of the separator shaft 20, and is inscribed in the bottom surface of the lug 24 in the center of the separator shaft 20. A rubber tube 25 is provided. Note that air is injected and discharged into the inside of the rubber tube 25 through the inside of the small diameter shaft portion 21 of the shaft 20, an air pipe 26 connected thereto, a rotary seal 27, and an air hose 28 by a pump (not shown). It has been made possible to do so. A predetermined number of disc-shaped disc guides 30 having an annular root portion 29 that loosely engages with the outer periphery of the separator shaft 20 are arranged on the outer periphery of the separator shaft 20 .

Adjustment of the width between the disc guides 30 of the separator guide according to the present invention having the above configuration is as follows:
Do it as follows.

That is, as shown in FIG. 4, when the air inside the rubber tube 25 is removed, the rubber tube 25 contracts, so that the projection of the lug 24 enters the hole 23. In this state, the disc guide 30 is loosely engaged with the separator shaft 20 in advance, so that it can be freely moved in the axial direction. By doing this, when each disc guide 30 is placed at a desired axial position and then air is injected into the rubber tube 25 via the air hose 28, air piping 26 and small diameter shaft portion 21, the air is removed within a few seconds. The rubber tube 25 expands as shown in FIG. 5 and pushes the lug 24 outward in the radial direction, and the protrusion of the lug 24 firmly engages the annular root portion 29 of the disc guide 30, which connects it to the separator. It is securely and concentrically fixed to the shaft 20. In this state, when slitting a metal strip of a predetermined amount and then slitting a metal strip of a different width, the air in the rubber tube 25 is similarly exhausted and the disc guide 30 is moved by a predetermined amount. Then, air may be injected into the rubber tube 25 again to fix it.

As is clear from the above description, the separator guide according to the present invention has the following advantages. In other words, conventionally, the width of the separator guide was changed according to the width of the metal strip, for example, from 0.5 to
However, according to the present invention, the width of the disc guide can be changed by simply expelling the air, moving the disc guide, and then injecting air again. Almost no time is required for reassembly, and the operating rate of the slitter can be greatly improved. Also,
There is no need to move heavy spacers during reassembly work, improving work safety. Furthermore, since no spacer is required, equipment costs can be significantly reduced.
